Statin therapy is associated with higher long-term but not perioperative survival after abdominal aortic aneurysm repair. J Vasc Surg 2018; 68:392-399.

Abstract
BACKGROUND Although preoperative and perioperative statin therapy improves postoperative outcomes in several populations, few data examine its association with survival after abdominal aortic aneurysm (AAA) repair. In addition, no data exist regarding the benefits of starting statins in patients with AAA not currently taking them. METHODS We performed a registry-based study of all patients undergoing repair of AAAs in the Vascular Quality Initiative between 2003 and 2017 without documented statin intolerance. In our primary analysis, we evaluated the association between preoperative statin therapy and long-term mortality, 30-day mortality, and in-hospital myocardial infarction and stroke. As a secondary analysis, we studied the cohort of patients not taking a statin preoperatively and compared their long-term mortality on the basis of whether they were discharged on a statin. To account for nonrandom assignment to treatment, we constructed propensity scores and applied inverse probability weighting. RESULTS We identified 40,452 AAA repairs, of which 37,950 fit our entry criteria (29,257 endovascular and 8693 open). Overall, 25,997 patients (69%) were taking a statin preoperatively, with patients undergoing endovascular aneurysm repair more frequently taking a statin than those undergoing open repair (69% compared with 66%; P < .001). After propensity weighting, preoperative statin therapy was not associated with 30-day death or in-hospital stroke or myocardial infarction. However, patients taking statins preoperatively experienced higher adjusted 1-year (94% vs 90%) and 5-year (85% vs 81%) survival from the date of surgery compared with those who were not (P < .001 overall), although subgroup analysis showed that this applied only to intact or symptomatic aneurysms. Of the 11,941 patients not taking a statin preoperatively and discharged alive, 2910 (24%) started on a statin before discharge. In our secondary analysis of the subset of patients not taking statins preoperatively, those initiated on a statin before discharge experienced higher survival at 1 year (94% vs 91%) and 5 years (89% vs 81%; P < .001 overall) than those who remained off statin therapy, with the greatest absolute long-term survival difference in patients with rupture (87% vs 62%; P < .001 overall). CONCLUSIONS Preoperative statin therapy is associated with higher long-term survival but not perioperative mortality and morbidity in patients undergoing AAA repair, and initiating statin therapy in previously statin-naive patients is associated with markedly higher survival. All patients with AAAs without contraindications should receive statin therapy. In patients not taking a statin at the time of AAA repair, clinicians should consider initiating one before discharge.

Abstract
OBJECTIVES The aim of the study was to compare short and long-term mortality and readmissions in patients with non-ruptured abdominal aortic aneurysm (AAA) treated with endovascular aortic repair (EVAR) or open aneurysm repair (OAR). DESIGN Retrospective survival analysis based on prospectively collected medical records of the national Polish public health insurer. MATERIALS In the National Health Fund database we identified all patients who underwent elective open or endovascular treatment of AAA between January 1st 2011 and March 22nd 2016. The data on mortality, selected concomitant diseases and readmissions were collected. A total of 7805 patients (mean age 70.9±8.1 yrs, 85.8% males) underwent OAR (n = 2336) or EVAR (n = 5469). A median follow up was 27.5 months (IQR range 10.0-38.4 months). METHODS The primary outcome variable was all-cause mortality, secondary outcomes included 30-day mortality and readmissions. Kaplan-Meier (K-M), Cox proportional-hazards and propensity score analyses were performed for primary and secondary outcomes adjusting for repair type of AAA (OAR vs. EVAR), age, sex and concomitant diseases. RESULTS EVAR patients had higher all-cause mortality (6.4% vs. 4.6% P = 0.002, adjHR 1.34, 95%CI 1.07-1.67, P = 0.010) compared with OAR. The mortality risks for OAR patients decreased below those for EVAR patients after 9.9 months. Of all the tested confounding factors only age independently and significantly influenced long-term mortality. Readmissions occurred more often in EVAR than in OAR (16.5% vs. 8.4% P<0.001, adjHR 2.15, 95%CI 1.84-2.52, P<0.001) independently from other covariants. Survival and readmissions Kaplan-Meier curves remained statistically different between OAR and EVAR patients after propensity score matching. CONCLUSIONS Survival benefit of EVAR over OAR disappeared early during the first year after procedure, particularly in patients below 70 years of age, accompanied by an increased frequency of readmissions of EVAR patients. Our data suggest re-evaluation of the strategy for AAA management in vascular units in the country.

Abstract
Abdominal aortic aneurysm (AAA) is defined as a permanent dilatation of the abdominal aorta that exceeds 3 cm. Most AAAs arise in the portion of abdominal aorta distal to the renal arteries and are defined as infrarenal. Most AAAs are totally asymptomatic until catastrophic rupture. The strongest predictor of AAA rupture is the diameter. Surgery is indicated to prevent rupture when the risk of rupture exceeds the risk of surgery. In this review, we aim to analyze this disease comprehensively, starting from an epidemiological perspective, exploring etiology and pathophysiology, and concluding with surgical controversies. We will pursue these goals by addressing eight specific questions regarding AAA: (1) Is the incidence of AAA increasing? (2) Are ultrasound screening programs for AAA effective? (3) What causes AAA: Genes versus environment? (4) Animal models: Are they really relevant? (5) What pathophysiology leads to AAA? (6) Indications for AAA surgery: Are surgeons over-eager to operate? (7) Elective AAA repair: Open or endovascular? (8) Emergency AAA repair: Open or endovascular?

Abstract
OBJECTIVE/BACKGROUND To achieve consensus on the minimum core data set for evaluation of peripheral arterial revascularisation outcomes and enable collaboration among international registries. METHODS A modified Delphi approach was used to achieve consensus among international vascular surgeons and registry members of the International Consortium of Vascular Registries (ICVR). Variables, including definitions, from registries covering open and endovascular surgery, representing 14 countries in ICVR, were collected and analysed to define a minimum core data set and to develop an optimum data set for registries. Up to three different levels of variable specification were suggested to allow inclusion of registries with simpler versus more complex data capture, while still allowing for data aggregation based on harmonised core definitions. RESULTS Among 31 invited experts, 25 completed five Delphi rounds via internet exchange and face to face discussions. In total, 187 different items from the various registry data forms were identified for potential inclusion in the recommended data set. Ultimately, 79 items were recommended for inclusion in minimum core data sets, including 65 items in the level 1 data set, and an additional 14 items in the more specific level 2 and 3 recommended data sets. Data elements were broadly divided into (i) patient characteristics; (ii) comorbidities; (iii) current medications; (iv) lesion treated; (v) procedure; (vi) bypass; (vii) endarterectomy (viii) catheter based intervention; (ix) complications; and (x) follow up. CONCLUSION A modified Delphi study allowed 25 international vascular registry experts to achieve a consensus recommendation for a minimum core data set and an optimum data set for peripheral arterial revascularisation registries. Continued global harmonisation of registry infrastructure and definition of items will overcome limitations related to single country investigations and enhance the development of real world evidence.

Practice Patterns of Fenestrated Aortic Aneurysm Repair: Nationwide Comparison of Z-Fen Adoption at Academic and Community Centers Since Commercial Availability.

Abstract
Context: Over the past decade, a number of endovascular approaches have evolved to treat aortic aneurysms with anatomy that is not amenable to traditional endovascular repair, although the optimal practice and referral patterns remain in question. The Zenith fenestrated (Z-Fen) endograft (Cook Medical) represents the first commercially available fenestrated graft product in the United States. Objective: We aim to quantify practice patterns in Z-Fen use during the first 5 years of commercial availability, and we identify predictors of high and low uptake. Design, Setting, and Patients: This is a retrospective review of complete order records for Z-Fen endografts since June 2012. We performed univariate and multivariate regressions of predictors that surgeons and centers would be in the top and bottom quartiles of annual Z-Fen use. Results: Since June 15, 2012, 744 surgeons have been trained to use Z-Fen, and 4133 cases have been performed at 409 trained centers. The average annual number of cases per trained surgeon was 4.46 [95% confidence interval (CI), 3.58-5.70]; however, many surgeons performed few or no cases following training, and there was a skew toward users with low average annual volumes (25th percentile 1.23, 50th percentile 2.35, 75th percentile 4.93, and 99th percentile 33.29). Predictors of high annual use in the years following training included academic center (aOR 5.87, P = .001) and training within the first 2 years of availability (aOR 46.23, P < .001). Conclusion: While there is literature supporting the safety and efficacy of Z-Fen, adoption has been relatively slow in an era when the vast majority of vascular surgeons have advanced endovascular skills. Given the training and resources required to use fenestrated or branched aortic endovascular devices, referral patterns should be determined and training should be focused on centers with high expected volumes.

Abstract
Abdominal aortic aneurysm (AAA) primarily affects male patients; however, female patients with AAA have a faster rate of aneurysm growth, have higher risk of rupture even at smaller diameters, and have worse outcomes following repair of ruptured and intact aneurysms. Furthermore, early natural history studies and randomized controlled trials evaluating surveillance versus repair in small aneurysms were conducted primarily in male patients. Therefore, there are limited data regarding the ideal threshold for elective repair of AAA in women, either by aortic diameter or by alternative measures. We review the existing literature regarding AAA in women and consider the most appropriate threshold for repair.

Abstract
OBJECTIVE This study aimed to analyze the spatial distribution and regional variation of the hospital incidence and in hospital mortality of abdominal aortic aneurysms (AAA) in Germany. METHODS German DRG statistics (2011-2014) were analysed. Patients with ruptured AAA (rAAA, I71.3, treated or not) and patients with non-ruptured AAA (nrAAA, I71.4, treated by open or endovascular aneurysm repair) were included. Age, sex, and risk standardisation was done using standard statistical procedures. Regional variation was quantified using systematic component of variation. To analyse spatial auto-correlation and spatial pattern, global Moran's I and Getis-Ord Gi* were calculated. RESULTS A total of 50,702 cases were included. Raw hospital incidence of AAA was 15.7 per 100,000 inhabitants (nrAAA 13.1; all rAAA 2.7; treated rAAA 1.6). The standardised hospital incidence of AAA ranged from 6.3 to 30.3 per 100,000. Systematic component of variation proportion was 96% in nrAAA and 55% in treated rAAA. Incidence rates of all AAA were significantly clustered with above average values in the northwestern parts of Germany and below average values in the south and eastern regions. Standardised mortality of nrAAA ranged from 1.7% to 4.3%, with that of treated rAAA ranging from 28% to 52%. Regional variation and spatial distribution of standardised mortality was not different from random. CONCLUSIONS There was significant regional variation and clustering of the hospital incidence of AAA in Germany, with higher rates in the northwest and lower rates in the southeast. There was no significant variation in standardised (age/sex/risk) mortality between counties.

Abstract
Abstract
Background
Lifelong postoperative surveillance is recommended following endovascular aneurysm repair (EVAR). Although the purpose is to prevent and/or identify complications early, it also results in increased cost and workload. This study was designed to examine whether it may be possible to identify patients at low risk of complications based on their first postoperative CT angiogram (CTA).
Methods
All patients undergoing EVAR in two Swedish centres between 2001 and 2012 were identified retrospectively and categorized based on the first postoperative CTA as at low risk (proximal and distal sealing zone at least 10 mm and no endoleak) or high risk (sealing zone less than 10 mm and/or presence of any endoleak) of complications.
Results
Some 326 patients (273 men) with a CTA performed less than 1 year after EVAR were included (low risk 212, 65·0 per cent; high risk 114, 35·0 per cent). There was no difference between the groups in terms of sex, age, co-morbidities, abdominal aortic aneurysm (AAA) diameter, preoperative AAA neck anatomy, stent-graft type or duration of follow-up (mean(s.d.) 4·8(3·2) years). Five-year freedom from AAA-related adverse events was 97·1 and 47·7 per cent in the low- and high-risk groups respectively (P < 0·001). The corresponding freedom from AAA-related reintervention was 96·2 and 54·1 per cent (P < 0·001). The method had a sensitivity of 88·3 per cent, specificity of 77·0 per cent and negative predictive value of 96·6 per cent to detect AAA-related adverse events. The number of surveillance imaging per AAA-related adverse event was 168 versus 11 for the low-risk versus high-risk group.
Conclusion
Two-thirds of patients undergoing EVAR have an adequate seal and no endoleak on the first postoperative CTA, and a very low risk of AAA-related events up to 5 years. Less vigilant follow-up after EVAR may be considered for these patients.

Abstract
OBJECTIVES Current management of ruptured abdominal aortic aneurysms (RAAA) varies among centres and countries, particularly in the degree of implementation of endovascular aneurysm repair (EVAR) and levels of vascular surgery centralisation. This study assesses these variations and the impact they have on outcomes. MATERIALS AND METHODS RAAA repairs from vascular surgical registries in 11 countries, 2010-2013, were investigated. Data were analysed overall, per country, per treatment modality (EVAR or open aortic repair [OAR]), centre volume (quintiles IV), and whether centres were predominantly EVAR (≥50% of RAAA performed with EVAR [EVAR(p)]) or predominantly OAR [OAR(p)]. Primary outcome was peri-operative mortality. Data are presented as either mean values or percentages with 95% CI within parentheses, and compared with chi-square tests, as well as with adjusted OR. RESULTS There were 9273 patients included. Mean age was 74.7 (74.5-74.9) years, and 82.7% of patients were men (81.9-83.6). Mean AAA diameter at rupture was 7.6 cm (7.5-7.6). Of these aneurysms, 10.7% (10.0-11.4) were less than 5.5 cm. EVAR was performed in 23.1% (22.3-24.0). There were 6817 procedures performed in OAR(p) centres and 1217 performed in EVAR(p) centres. Overall peri-operative mortality was 28.8% (27.9-29.8). Peri-operative mortality for OAR was 32.1% (31.0-33.2) and for EVAR 17.9% (16.3-19.6), p < .001, and the adjusted OR was 0.38 (0.31-0.47), p < .001. The peri-operative mortality was 23.0% in EVAR(p) centres (20.6-25.4), 29.7% in OAR(p) centres (28.6-30.8), p < .001; adjusted OR = 0.60 (0.46-0.78), p < .001. Peri-operative mortality was lower in the highest volume centres (QI > 22 repairs per year), 23.3% (21.2-25.4) than in QII-V, 30.0% (28.9-31.1), p < .001. Peri-operative mortality after OAR was lower in high volume centres compared with the other centres, 25.3% (23.0-27.6) and 34.0% (32.7-35.4), respectively, p < .001. There was no significant difference in peri-operative mortality after EVAR between centres based on volume. CONCLUSIONS Peri-operative mortality is lower in centres with a primary EVAR approach or with high case volume. Most repairs, however, are still performed in low volume centres and in centres with a primary OAR strategy. Reorganisation of acute vascular surgical services may improve outcomes of RAAA repair.

Abstract
BACKGROUND Complex abdominal aortic aneurysm (AAA) is a relatively common presentation to the vascular specialist. Despite this there is little consensus on how to manage the often comorbid group of patients. Recent advances in endovascular technology have led to the availability of multiple devices, many of which could be used to treat the same aneurysm. The aim of this study was to quantify this potential variability across vascular specialists from multiple countries. METHODS An online survey was emailed to members of the Vascular Society for Great Britain and Ireland (VSGBI), the Canadian Society for Vascular Surgery (CSVS) and the Australian and New Zealand Society for Vascular Surgery (ANZSVS). The survey presented a vignette of a 63-year-old woman with significant respiratory comorbidity and a 54 mm juxtarenal AAA (7 mm neck). There were no other adverse morphological features for endovascular repair. The survey included images and questions related to management of the aneurysm. RESULTS The survey received 238 responses; 61 from ANZSVS, 65 from CSVS and 112 from VSGBI. VSGBI specialists were significantly more likely to continue surveillance than both ANZSVS (odds ratio [OR] 3.41, 95% confidence interval [CI] 1.61-7.65; P<0.001) and CSVS counterparts (OR 2.61, 95% CI: 1.29-5.47; P<0.01). ANZSVS specialists were significantly more likely to perform an endovascular repair than those from CSVS (OR 3.28, 95% CI: 1.50-7.40; P<0.01) and VSGBI (OR 3.65, 95% CI: 1.81-7.59; P<0.001). CSVS specialists were significantly more likely to manage the aneurysm with open surgery than colleagues from the VSGBI (OR 6.57, 95% CI: 2.58-18.46; P<0.001) and ANZSVS (OR 7.18, 95% CI: 2.22-30.79; P<0.001). CONCLUSIONS Significant variation in the management of a juxtarenal AAA between countries was observed. The same patient would be more likely to have an endovascular repair in Australia and New Zealand, open surgery in Canada and continuing surveillance in the UK and Ireland. This variation reflects the lack of long-term evidence and international consensus on the optimal management of complex AAA.

Abstract
BACKGROUND To assess the relation of abdominal aortic aneurysm (AAA) diameter with the proximal neck anatomy (PNA) hostility and to evaluate its impact on the endovascular aneurysm repair (EVAR) outcomes with the use of newer generation endografts. METHODS Retrospective analysis of single institution's recorded data from February 2009 to April 2016. Patients' characteristics, comorbidities, aortic morphology, perioperative characteristics and outcomes were analyzed. In relation to AAA diameter 2 groups were identified: group A (50-55 mm) and group B (>55 mm). Hostile PNA was defined based on: neck diameter >28 mm, length <15 mm, angulation >60o, and circumferential thrombus and/or calcification >50%. The aortic neck scoring system was calculated. Multiple logistic regression analysis with a forward likelihood ratio method adjusted for age and gender was undertaken. RESULTS Three hundred seventeen patients (96% males, mean age 72.4±9 years, 80% elective) were follow-up for a mean of 23.4 months (range, 3-86 months). No differences were observed in demographics and co-morbidities between the two groups (group A: 134, 42% vs. group B: 183, 58%). Hostile PNA was present in 147/317 (46%) patients and significantly more likely to be present in group B (P<0.001). In group B the aortic neck score was higher (P<0.001), the likelihood for having hostile PNA increased for neck diameter by 2.2-fold (OR 2.2, P=0.013, 95% CI: 1.18-4.03), length by 2.3-fold (OR 2.3, P=0.012, 95% CI: 1.20-4.51), angle by 4.8-fold (OR 4.8, P=0.002, 95% CI: 1.79-13.24) and presence of thrombus by 1.5-fold (OR 1.5, P=0.037, 95% CI: 1.45-10.34). No association existed for neck calcification (P=0.071). Technical success, adjunctive procedures, perioperative characteristics and outcomes were comparable in friendly and hostile PNAs. CONCLUSIONS PNA hostility is more likely in AAA with diameter >55 mm but with the use of newer generation endografts this did not influence the short- and mid-term EVAR outcomes. Longer follow-up is needed for a more definite conclusion.

Abstract
Abstract. Background: We analysed trends in mortality of endovascular (EVAR) and open aortic repair (OAR) in patients hospitalized for abdominal aortic aneurysms (AAA) in Germany from 2005 to 2015. Patients and methods: We used national statistics published by the Federal Statistical Office in Germany to calculate mortality rate of patients hospitalized with ruptured (rAAA, n = 2,448 in 2005, n = 2,180 in 2015) and non-ruptured (iAAA, n = 11,626 in 2005, n = 14,205 in 2015) AAA. Results: Considering only those who were treated with EVAR or OAR, treatment rates of iAAA with EVAR increased to 78.2 % in males and 72.6 % in females in 2015 and treatment rates of rAAA to 36.9 % and 40.7 %, respectively. In cases with iAAA, death rates associated with EVAR decreased in males from 2.1 to 1.1 % (p = 0.0005) in the period from 2005 to 2015 but not in females (1.8 % in 2005 and 2.3 % in 2015, p = 0.8511). Similar trends are seen in cases with rAAA (males 30.1 % and 24 %, p = 0.1034, females 36.4 to 37.3 %, p = 0.8511). Death rates associated with OAR increased in males from 4.7 % in 2005 to 5.7 % in 2015 (p = 0.0103) and tended to increase in females from 6.8 to 8.2 % (p = 0.1476). In cases of rAAA, there were no changes. EVAR treatment rates increased in cases with iAAA in both genders with age, as well as in males with rAAA, but not in females. OAR associated death rates increased with age in rAAA (from around 30 % in the sixth/seventh decade of life to almost 80 % in cases with patients over the age of 90) and in iAAA (from 1.1 to 20 %). Conclusions: The general increase in EVAR procedures in males and females hospitalized for rAAA and iAAA went along with a decrease in in-hospital mortality in males treated with EVAR for iAAA only and an increasing mortality in males treated with OAR for iAAA.

Abstract
Background The epidemiology of abdominal aortic aneurysm (AAA) is changing. Outcomes for aortic surgery have improved. However, the accepted guideline for the management of AAAs has remained unchanged over the last 2 decades. We aimed to gain insight into the patients' experience while they are managed under the traditional clinical pathway. Method With the help of a patient focus group, we designed a survey to assess the patients' perception of the disease and their experience during different stages of the AAA clinical care pathway (surveillance, perioperative care, postoperative follow-up). An invitation to participate in the survey was sent to all patients with AAA who were receiving care at the Oxford Regional Vascular Services Unit, part of the Oxford University Hospitals NHS Trust. Results We received 194 responses from patients with AAA. One hundred seventy-seven were male, with a median age of 75 to 79 years. Just over a third had undergone surgery already, and the remaining 63% were either in surveillance or awaiting surgery. Their experience during the AAA management pathway was mostly positive. Of the issues that were most important to them in terms of their medical care, the provision of explanation and regularity of monitoring stood out as the most common considerations. Conclusion Patients are generally satisfied with the care they received, but there is room for improvement. They have also highlighted key areas that are most important to them in terms of their medical care. These should guide the future direction for quality improvement and research.

Abstract
BACKGROUND The Rapid Ruptured Abdominal Aortic Aneurysm Score (RrAAAS) was developed from Vascular Study Group of New England (VSGNE) data (649 ruptured abdominal aortic aneurysm (rAAA) patients, repaired both open and endovascularly), using preoperative age, creatinine, and blood pressure. This study validates that model using the larger National Vascular Quality Initiative (VQI) data set and compares its performance to previous models. METHODS The VQI registry was queried for patients undergoing rAAA repair from 2006 to 2016. The performance of our original model, RrAAAS, was tested on this data set excluding VSGNE patients (VQI minus VSGNE), and its performance was then compared to the performance of the Glasgow Aneurysm Score (GAS) and Edinburgh Ruptured Aneurysm Score (ERAS). RESULTS VQI contained 2,704 eligible patients, of which 715 had been contributed by VSGNE. The discrimination of RrAAAS was similar to GAS or ERAS (area under a receiver operator characteristic curve = 0.66). Neither GAS nor ERAS provides a direct prediction of mortality; observed mortality in the VQI minus VSGNE cohort tended to be somewhat lower than predictions of the original RrAAAS. A recalibrated equation predicting the percent mortality was Mortality (%) = 16 + 12*(age > 76) + 8*(creatinine > 1.5) + 20*(systolic blood pressure < 70). CONCLUSIONS The previously described RrAAAS has similar discrimination as the GAS and ERAS, is easier to obtain in an emergency setting, and has been recalibrated to reflect the experience of a large national sample. The RrAAAS could be useful for clinicians caring for these patients and could be used for risk adjustment when comparing regional differences in mortality associated with rAAA repair.

Abstract
Endovascular aneurysm repair (EVAR) has gained increasing popularity in the treatment of infrarenal abdominal aortic aneurysm. Despite its favorable early outcomes, the long-term efficacy of EVAR remains a concern. Late rupture is the ultimate treatment failure and continues to complicate EVAR. Univariate and multivariate analyses have identified factors predictive of late rupture. The importance of EVAR surveillance to prevent late complications is equally widely acknowledged. This article aims to present our current understanding of the precipitating factors of late rupture after EVAR and explores whether the key to its prevention lies within improving patient factors, particularly compliance to follow-up appointments or whether physicians hold the solution.

Abstract
The Society for Vascular Surgery Vascular Quality Initiative is a patient safety organization and a collection of procedure-based registries that can be utilized for quality improvement initiatives and clinical outcomes research. The Vascular Quality Initiative consists of voluntary participation by centers to collect data prospectively on all consecutive cases within specific registries which physicians and centers elect to participate. The data capture extends from preoperative demographics and risk factors (including indications for operation), through the perioperative period, to outcomes data at up to 1-year of follow-up. Additionally, longer-term follow-up can be achieved by matching with Medicare claims data, providing long-term longitudinal follow-up for a majority of patients within the Vascular Quality Initiative registries. We present the unique characteristics of the Vascular Quality Initiative registries and highlight important insights gained specific to open and endovascular abdominal aortic aneurysm repair.

Abstract
BACKGROUND The reported 54 mm median intervention diameter for endovascular aneurysm repair (EVAR) in the Vascular Quality Initiative and European data from the Pharmaceutical Aneurysm Stabilisation Trial (PHAST) implies that in real life the majority of abdominal aortic aneurysm (AAA) repairs occur at diameters smaller than the consensus intervention threshold of 55 mm. This study explores the potential consequences of this practice. METHODS The differences between real life AAA repair and consensus based intervention threshold were explored in reported data from vascular quality initiatives and PHAST. The subsequent consequences of advancement of endovascular aneurysm repair (EVAR) were estimated using a multistate model based on life tables for the EVAR Medicare population. RESULTS There appears an approximate 5 mm difference in AAA diameter between real life practice and consensus intervention threshold. Assuming a 2.5 mm annual growth rate, this results in an approximately 2 year advancement of AAA repair. According to the model used, early repair reduces overall small aneurysm patient mortality by 2.3%, it results in 21.9% more EVAR procedures, more EVAR related deaths, and 42.3% and 36.8% more open and endovascular re-interventions, respectively. Cost-benefit estimates imply 482 fewer AAA related deaths, but 140 extra EVAR related deaths for a population of more than 30,000 AAA patients, and a 300 million USD increase in health costs for the 8 year observation period in the Medicare population. CONCLUSIONS In the real life situation a large proportion of EVAR procedures appear to occur before reaching the consensus threshold. Although this reduces mortality, it comes at a cost of approximately 1 million USD per prevented rupture related death.

Abstract
BACKGROUND The epidemiology and management of abdominal aortic aneurysms (AAAs) has changed drastically in the past decades, with implementation of nationwide screening programs, introduction of endovascular repair (EVAR), and reduced prevalence of the disease. This report aims to assess recent trends in AAA repair epidemiology in Sweden in this context. METHODS Primary AAA repairs registered in the nationwide Swedish Vascular Registry (Swedvasc) 1994-2014 were analyzed regarding patient characteristics, repair incidence, technique, and outcome. Four time periods were compared: 1994-1999, 2000-2004, 2005-2009, and 2010-2014. RESULT The incidence of intact AAA repair increased (18.4/100,000 1994-1999, 27.3/100,000 2010-2014, p < .001) predominantly among octogenarians (12.7/100,000 1994-1999, 36.0/100,000 2010-2014, p < .001). The utilization of EVAR increased (58% of all intact AAA repairs 2010-2014), especially among octogenarians (80% 2010-2014). During the last time period, however, the incidence of intact AAA repair stabilized, despite an increasing number of screening-detected AAAs operated on (19% in 2010-2014). Short- and long-term outcome after intact AAA repair continued to improve, most pronounced among octogenarians (30-day mortality 9% 1994-1999, 2% 2010-2014, p < .001). The incidence of ruptured AAA repair steadily decreased (9.2/100,000 1994-1999, 6.9/100,000 2010-2014, p < .001) and the use of EVAR for ruptures increased (30% in 2010-2014). The previously observed improvement of short- and long-term outcome after ruptured AAA repair (30-day mortality 38% 1994-1999, 28% 2010-2014, p < .001) stalled during the last time period. The overall 30-day mortality after ruptured AAA repair was 22% after EVAR versus 31% after open repair in 2010-2014. The corresponding mortality for octogenarians was 28% versus 42%. CONCLUSIONS For the first time, a halt in intact AAA repair workload could be identified. This trend-break occurred despite continued increase in treatment of octogenarians and screening-detected aneurysms. Additionally, the ruptured AAA repair incidence continued to decrease. These findings, together with the sustained improvement in survival after AAA repair, may have important impact on planning of vascular surgical services.
